  Purpose
To assess the efficacy and safety of Tygacil in the usual German hospital setting. The main goals are: to assess the efficacy of Tygacil under usual care conditions (cure rate); to assess the main side effects observed in daily medical practice (Safety of Tygacil); to determine whether patients are optimally dosed with Tygacil (according to the label) and the proportion of patients receiving a monotherapy versus combination therapy; to observe the potential resistance development against Tygacil in Germany; to determine which antibiotic agents are chosen for a combination therapy with Tygacil; to determine to which antibiotic substance non-responders to Tygacil are switched; to assess the duration of the intravenous therapy with Tygacil and to determine whether and which patients receive an oral antibiotic substance after the therapy with Tygacil; to collect information on profile, comorbidities and characteristics of patients treated with Tygacil.

Condition Intervention
Infection Drug: tigecycline

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Non-Interventional Study To Evaluate The Safety And Effectiveness Of Tygacil In The Treatment Of Patients With Complicated Intra-Abdominal Infections Or Complicated Skin And Skin Structure Infections

Primary Outcome Measures:
  • Percentage of Participants With Clinical and Microbiological Cure: All Participants [ Time Frame: End of Treatment (duration based on severity, location, and clinical response; maximum duration 47 days) ]
    Cure = complete resolution of infection symptoms; no further antibiotic treatment required. A second microbiological examination was documented only for participants with treatment failure.

  • Percentage of Participants With Clinical and Microbiological Cure: Nosocomial Infections [ Time Frame: End of Treatment (duration based on severity, location, and clinical response; maximum duration 47 days) ]
    Cure = complete resolution of infection symptoms; no further antibiotic treatment required. A second microbiological examination was documented only for participants with treatment failure.

  • Percentage of Participants With Clinical and Microbiological Cure: Community-acquired Infections [ Time Frame: End of Treatment (duration based on severity, location, and clinical response: maximum duration 47 days) ]
    Cure = complete resolution of infection symptoms; no further antibiotic treatment required. A second microbiological examination was documented only for participants with treatment failure.

  • Percentage of Participants With Composite Cure: All Participants [ Time Frame: End of Treatment (duration based on severity, location, and clinical response; maximum duration 47 days) ]
    Composite Cure = complete resolution or improvement of infection symptoms; no further antibiotic treatment required.

  • Percentage of Participants With Composite Cure: Nosocomial Infections [ Time Frame: End of Treatment (duration based on severity, location, and clinical response; maximum duration 47 days) ]
    Composite Cure = complete resolution or improvement of infection symptoms; no further antibiotic treatment required.

  • Percentage of Participants With Composite Cure: Community-acquired Infections [ Time Frame: End of Treatment (duration based on severity, location, and clinical response: maximum duration 47 days) ]
    Composite Cure = complete resolution or improvement of infection symptoms; no further antibiotic treatment required.


Secondary Outcome Measures:
  • Participants With Probable Failure at Follow-up [ Time Frame: Follow-up (up to Day 47) ]
    Participants with antibiogram follow-up due to treatment failure who had detectable pathogens. Treatment failure = no significant improvement of infection symptoms under Tygacil therapy.

  • Percentage of Participants With Resistant Pathogens Identified at Follow-up Due to Treatment Failure [ Time Frame: Follow-up (up to Day 47) ]
    Percentage of participants with resistant pathogens for each pathogen identified at second (follow-up) microbial examination. A second microbiological examination was documented only for participants with treatment failure. Treatment failure = no significant improvement of infection symptoms under Tygacil therapy.

  • Antibiotic Agents Chosen for Combination Therapy With Tigecycline [ Time Frame: Baseline to End of Treatment (up to Day 47) ]
    Percentage of participants who received each antibiotic administered as combination therapy with tigecycline.

  • Change of Antibiotic Treatment From Tygacil to Alternative Antibiotic [ Time Frame: Baseline to End of Treatment (up to Day 47) ]
    Reasons for change in antibiotic treatment from Tygacil to another antibiotic.

  • Reasons for Utilization of Tygacil [ Time Frame: Baseline to End of Treatment (up to Day 47) ]
  • Overall Mortality: All Participants [ Time Frame: Baseline to End of Treatment (up to Day 47) ]
    Deaths for any reasons occurring during the study observation period.
